You are probably going to have to use a Thread. I.e. Loop through the  
downloads in a new Shoes thread and update a para external to that  
thread.

Some examples of threading:

http://thread.gmane.org/gmane.comp.lib.shoes/842/focus=846

And the progress bar I did here:    
http://github.com/i5m/shoeset/blob/master/shoeset.rb

There could be another way aswell. Sure someone else will have some  
input.

Thanks. That did the trick.

Awesome. I'll look this over too.

Hi Trans,

Good question. Interesting! How about this one? ;-)

Shoes.app do
  urls = %w[

   ]

  button "Fetch" do
    urls.each do |url|
      fname = File.basename(url)
      download url, :save => fname do
        stack do
          para url, :stroke => green
          image fname
        end
      end
    end
  end
end


Hope this helps,

Even better. Smart _why.

Ah, the download method. :) I remember now, _why put that in to get around
explicitly threading it, so that we could just do it async, like as is done
in Prototype, jQuery, and a bunch of other javascript libs.
